One Protocol, Many Modes of Communication New SIP-enabled converged communications solutions enable users to interact with each other or with an application, in a variety of ways. Input can be via speech, keyboard, telephone keypad, or mouse. Various modes of output may include synthesized speech, audio, plain text, motion video, and/or graphics. And best of all — you control how people reach you. Here are some examples that SIP-enabled solutions can facilitate: Voice/IM/video: A common interface provides access to instant messaging, voice, and video services, tied together with presence. Initiating communications is the same for all modalities, and users can switch from one communication method to another on the fly to best meet their needs. Inline translation services: A SIP request, originating with an English-speaking user, might contain a Web services request to translate a message into another language for a non-English-speaking recipient. Multimodal messaging: A SIP-enabled voice messaging system could provide features such as: • Voice-mail headers to the end-user via text • Display-enhanced voice-mail by delivering text or graphics menus instead of voice-based menus • Virtual business cards with every voice call so that the user can have the caller’s contact information available • Playback, skip, rewind, pause, slowdown, and speedup buttons using a graphical user interface (GUI) in a screen phone.
